Zusammenfassung:	To provide a carbon dioxide reduction catalyst that can form a hydrocarbon having 5 or more carbon atoms with high efficiency even at a high flow rate.SOLUTION: A carbon dioxide reduction catalyst hydrogenates carbon dioxide to reduce carbon dioxide, producing a hydrocarbon. The carbon dioxide reduction catalyst comprises Fe and Ga as catalyst metals. In the catalyst metals, the Ga content is 10-30 mass%. Preferably, the Ga content should be 20-30 mass%. Preferably, the catalyst metals comprise an Fe-Ga complex oxide composed of Fe and Ga.SELECTED DRAWING: Figure 1 【課題】高流速下においても炭素数が５以上の炭化水素を高効率で生成可能な二酸化炭素還元触媒を提供すること。【解決手段】二酸化炭素を水素化反応させて二酸化炭素を還元し炭化水素を生成する二酸化炭素還元触媒であって、触媒金属として、Ｆｅ及びＧａを含み、触媒金属中にＧａは１０～３０質量％含まれる、二酸化炭素還元触媒。Ｇａは２０～３０質量％含まれることが好ましい。触媒金属は、Ｆｅ及びＧａにより形成されるＦｅ－Ｇａ複合酸化物を含むことが好ましい。【選択図】図１
